CAR-COUPLING.

SPECIFICATION forming part of Letters Patent 'No. 259,502, dated June13, 1882.

Application filed April 18, 1882.

To all whom it may concern Be it known that we, ELMER A. CONVERSE andNATHANIEL T. GRIFFIN, of Monticello, in the county of Van Wert and Stateof Ohio, have invented a new and Improved (Jar-Coupling, of which thefollowing is a full, clear, and exact description.

This improvement in car-couplings consists of a eontrivance of thecoupling-pin so that the link will raise it automatically and coupleself-actingly when the cars come together, the object being to avoid thedangers of going between the cars for coupling them in the ordinary way,as hereinafter described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figurel is alongitudinal sectional elevation ofourimprovedear-conplingon line 00 w, Fig.2; and Fig. 2 is a horizontal section ofone of the draw-bars and plan view of the other, the sec tion beingtaken on line 3 3 of Fig. 1.

A represents the heads of the draw-bars, which are similar to those ofordinary use, except that we prefer to make them a little longer fromthe front ends to the shoulder B than usual, and we make the oblongmortises O for the coupling-pins D, instead of the round hole of theusual form. Instead of using round pins we employ broad flat plates, asshown, setting them edge-wise to the links F, and making the curved formof the lower ends so that when the end of thelink strikes said curvededges it will force the pins up, and thus couple the cars by (No model.)

the mere contact of the two cars together, and thereby avoid thedangerous practice of going between the cars to hold-11p the pin anddrop it by hand.

The pins are constructed with a slot, H, and secured against beingthrust out of the drawbars by a pin, I, fitted on the upper side of thedraw-head and through the slot H.

For box-cars the coupliugpins may have a chain, J, extending to the topfor pulling the pins up to uncouple the cars, and for flat cars a leverextending from the side of the car may be used, the inner end beingcoupled to the pin by the chain.

The pins drop at the points into the holes K in the lower parts of thedraw-bars, so as to hear at the back L to prevent bending when the linkstrikes. The pins draw in the mortises O in the upper sides of thedraw-heads for pulling the cars.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent In a car-coupling, the flexibly-suspendedplate-pin D, made fiat, curved at the front lower edge, and slotted atH, in combination with a draw-bar having a cross-pin, I, in its topslot, and a lower slot of less length than the width of the plate, asshown and described.
